;Application filedOctober 14;, 1911. Serial No. 654,750.

To all whom itmag concern: 1 Be it known that I, JOHANN. CARL Mun LER, asubject of the German Emperor, and residing in Dresden, in the Kingdom of Saxony, Germany, have invented certain new and. useful Improvements in Apparatusfor Covering the Tip ,Ends of Gigarette Paper with Gold-Leaf.

My invention relatesto the separation of the leaves of gold which are to be used on the cigarette mouth-pieces from the oompound strip which is formed into .a continuous roll; and further, to the attachment of the separated leaf of gold. to the strip of cigarette-paper. The strip of covering material, consisting of gold leaf, is as usual wound intoa con tinuous roll in connection with an underlying strip ofwrapping-paper. By means of my invention I separate the'covering gold leaf, without cutting the underlying strip with thesknife used therefor. And afterward I bring the separated leaf on to the place of the continuous and continuously moving strip of cigarette paper, (already prepared with adhesive material for this purpose) by holding thisportion of the strip still for aishort period of time, without,

however, interruptingthe movement of the entire strip.

As regards the separation ofthe. covering leaf-it has been long knownhow to eflect 7 this by a draw out, without. cutting through the underlying strip. By this operation. the knife was pressed down only so far asto cut the covering material, without cuttingthe underlay. The extremely exact adjustment of the knife which ishere necessary, is very difiicult to effect, and canitakeno accountof any inequalities in the underlying -;stri-p. WVhen, however, this underlying-strip is injured at anysuch place, it tears, and cannot serve further to bring the cut-oifleaf to the gummed portion of the strip of cigarette paper. U

. According to my invention, the knife is not positively guided, but this is effected 1 its own weight orby the action'of aspring;

Thereby the knife exerts on fthe material which is to be out only that amount of pressure which is necessaryto separate the covering gold-leaf, and that where irregularities 5 in thickness etc, of the, underlying strip em ist,...the vknife can giveiwayto the requisite degree. Naturally, either the weight of the ,knifeitself, or. the force of the springwhich;

regulates its pressure, can be regulated ininutely and exactly. After the separation of thealeaf it must be gummed to. the continm ous and regularly continuously-moving strip of cigarette-paper;thatis, this stripmust be covered atproper distance apart with covering leaf ln order to effect this, thedownward-.movlngstr p of cigarette paper must temporarily remain motionless in the pressing device that is, the portion which is to be gilded must remain motionless for a short per od of time. My inventionenables the portion of the. strip in question to "remain motionless in the pressing appliance, while at the sametime permitting continuous, unnterrupted motion of the wrappersstrip to and from the portion to be covered or gilded; a result which is advantageous from the standpoint of safetyagainst, the breaking of the delicate strip; ofcigarette-paper at the time-of approach. ,Tl estopping of the portion of the strip ino question accomplished insuch a man I ner that' a relative shifting. between the strip and ,thafeed-rolls is effected. Forv this purpose there are two feed-rolls on a carriage,

which is regularly reciprocated by a suitable mechanisnnand also a non-reciprocating feed roll. this means, there is formed in the strip of cigarette-paper a U -sha'ped loop or bight. Y

The new device is represented on the accompanying drawing in two different forms of construction,, in both of which the same reference-letters andnumerals are employed, and injwhioh Figure 1 is;a. side-view,partly in longitudinal section, Fig.2 is a vertical trans- .versesection on the line2 -2, of Fig. 1, Fig.

3 is adetail side and'top-view of the cam rollers shown in Fig. 2, and Fig. 4 is-a side.- view of another form of construction.

' The 'roll A is formed in the usualmanner I underlying strip of ordinary paper; .The Y of a strip of covering 1 gold-leaf and an coveringrstrip is fed lover a horizontal table B; from zthisthe underlying strip C is fed' 7 over a roll Dindownwarddirection. The

with-"it; of the covering gold-leaf is effected feed motion of the, underlying strip C, and i by the eccentric pin F and the roll G. The

Hat one end of the machine; the knifeholder is laterally shiftable on the horizontal axle 0. The knife-holder is constantly pressed by a helical spring-d, which is wound about the aXle 0, toward the part H of the frame, that is, in the direction of the arrow, shown in Fig. 2. On the hub of the knife-holder is arranged a semi-annular cam c which projects downwardly. Against this cam abuts the inner-end of a pin f, which is horizontally shiftable in a sleeve of the part H of the frame, as shown in Fig. 2. A horizontally-shifting motion of the knife-holder 6 against the pressure of the spring (Z is imparted by means of a roller 9 which acts intermittently against the outer end of the pin f. This roller 9 is journaled ona disk h, which is formed into a spur-wheel at its circumference and which is rotated from the driving-shaft of the machine. The roller 9 is. placed rotatably on the end of a screw-bolt g, which adhesive transmitting 6 is screwed into a cylindrical socket attached to the disk It by means of the plate g and suitable fastenin -screws, as shown in Figs. 2 and 3.

The movement of the pin f, which at the same time effects the shifting of the knife a over the covering-strip of gold-leaf, takes place at that instant of time,when the covering-strip is in a state of rest. The pressure of the knife on the covering-strip is determined only by the weight of the knife itself, and is so calculated that during its lateral mot-ion the. knife exerts a drawcut through the covering-strip of gold-foil only, but not through the underlying strip of or dinary paper.

After the separation of the covering-strip of gold-leaf has taken place, it is united with the tip-end of the strip of cigarettewrapperE, which has been covered locally for that purpose with adhesive material. This strip E runs over the guide-roll l and is in the usual manner coveredwith adhesive material while passing between the roll 2 and the carrier 3 for the adhesive material, and then conducted over the guide-rolls i, 5 and 6. The adhesive material is supplied to the surface of the carrier 3 at each rotation of the same in the usual manner by an contact-roll (not shown). At the emerging point there is effected an intermittent mo'vement of the strip E by any desired means. The guiderolls 4 and 5 are journaled on the carriage 7, which by appropriate mechanism is reciprocated to a regulatable extent. This reciprocation takes place at the same speed as that'of the strip of cigarette-wrapper and is accomplished in any suitable manner.

In the neighborhood of the loop or bight formed by the strip of cigarettepaper be tween the rolls 4, 5 and 6, is located a cuttingtable B. Over this runs, as already described, the cont-inuously-moving compound strip consisting of the covering strip of gold-leaf and an underlying strip of ordinary paper. 'The pieces of gold-leaf sepa space for the return-motion of the carriage 7 andits roll .i. Any suitable mechanism for reciprocating the presser-piece 15 at the proper time may be employed.

In the form of construction, shown diagrammatically in Fig. 4, the upper shiftable roll 1 assumes the function of the presserpiece 15, which is dispensed with, as the roller 4: is rolled over the layers of underlying paper, covering-strip of gold-foil and cigarette-paper, then moving over the cutting-table B. In this case an oscillating movement of the table B against the roll 4, and a corresponding shifting is required, in order that after the covering of the tip-end of the cigarette-paper which is to be gilded, there may take place a relative clearance between the table B and the roll 4:, to permit the free passage of the strip of cigarettepaper and the covering-strip of gold-foil. The cutting-table B is therefore made movable about the pin 16, and is lifted from time to time into contact with the roll 4 by the cam 17 and pinlS. The table B is lowered again so that the combined strip of cigarette-paper and layer of gold-foil can be moved forward freely.

When the carriage 7'1noves to the left with the same speed as the unintermittentlymoving strip E, the following occurs: The U-shaped' loop or bight, which is formed by the inward motion of the strip E by the rolls 4 and 5, is'moved to the left, which occasions the shifting of the lower portion of this loop, the length of which is naturally limited by the non-variable distance between. the rolls t and 5 as far as it consists of newly-arriving strip-material, over the cutting-table B. I

Over the roll 5 the strip E passes at the same rate of speed as that 'of the newly arriving looped portion of the cigarettepaper. As now, according to the form of construction shown in Fig. 1, the length of I same time the transfer, by rolling on, of the covering material, it is not'necessary to have, when the carriage 7 returns, anon-moving loop of considerable extent between the rolls 4 and 5; the distance between the rolls 4 and 5 need not be greater than the stroke of the carriage.

The regular feed of the strip of cigarettepaper may take place without hindrance, because the roll 5 approaches the roll 6 with the same speed as that of the strip; so that the downward movement of the strip can take place on account ofthe shortening of the loop between the rolls 6 and 5. Also the inward feed of the strip can take place regularly, because its approach corresponds to the movement of the roll 4 toward the left.

When the carriage 7 returns (that is, moves to the right in the drawing) a double length of strip will approach; as at this pe riod the roll 4 moves toward the approaching strip. This double forward feed is, however, taken up by the lengthening of that portion of the strip betwen the rolls 5 and 6; the strip at the same time receding uninterruptedly from the roll.

At its front end the carriage 7 is provided with an oblique surface; and at the front end of the knife-holder there is a roll 2', which runs on the oblique surface of the carriage. By this means, after-the covering-leaf is separated, the knife-holder is lifted above the table 13. After this has taken place, the table B, over which the covering material passes, sinks. During this downward movement, which is effected by the cam disk 17 and the roll 18, the forward feed of the covering material takes place; at the same time the carriage 7 moves back, and the knife-holder returns downward to the position shown in ,Fig. 1, for cutting off the next covering-piece of goldfoil.
